1 Claim. 1

This invention relates to heating apparatus.

It is an object of the present invention to provide a compact heatingapparatus particularly adapted for use with electric current and Whereinthe water is fed by a pump to a large vessel centrally located withinthe apparatus and is extended from the vessel through a plurality ofcoils located in sections at difierent locations within the apparatusand returned to the pump, adequate means being provided to supply thesystem with any loss of water and wherein there is forced through theapparatus air which will pass to various outlet pipes in the top of theapparatus.

It is another object of the present invention to provide an electricheating furnace wh ch is of simple construction, inexpensive tomanufacture, and efiicient in operation.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnection with the accompanying drawing, in which:

Fig. 1 is an elevational view of the heater embodying the features ofthe present invention.

Fig. 2 is a transverse sectional view taken on line 2--2 of Fig. 1.

Fig. 3 is a sectional view, in elevation, taken on line 33 of Fig. 1.

Fig. 4 is a transverse sectional View taken on line 44 of Fig. 3.

Referring now to the figures. l9 represents a bottom floor on which ismounted inner and outer casing Walls H and 2 with insulation ittherebetween. In the top of the furnace is a dished plate portion 54 fordeflecting heat and below this portion the apparatus casin is of conicalshape and hot air outlets extend outwardly and upwardly therefrom asindicated at 15. These outlets are circumferentially spaced about thetapered or conical top of the casing.

Within the casing and. supported upon legs 16 is a large vessel H whichis closed at the top and bottom and adapted to contain water to beheated. Extending into the vessel are electric heating units l8 and I9and thermostats 20 and 2| located respectively adjacent the electricheating units. These electric heating units are sufficient to bring theWater within the vessel I! to a boiling point. Preferably the water iskept below the boiling point but close thereto.

On the top of the casing and at one side thereof is a water supply tank23 having a water inlet pipe 24 and a float Valve device 25 forcontrolling the inward flow of water to the supply tank 23. Water leavesthe bottom of the tank through a pipe 26 and is caused to be circulatedby a pump 2 21 and forced into the vessel I! through a pipe 28.

At the top of the vessel I! is an outlet 29 leading to a copper coil 3|which lies above the vessel ll. From this coil through a pipe portion 32the water extends to a larger coil 33 which surrounds the vessel ll. Thewater returns to the pump Zl through pipe portion 34. The same water iscontinually used and is only replenished when necessary by water fromthe supply tank 23.

At the bottom of the case and adjacent to the floor it! is an an airinlet 36 in which there is a circulating fan 31 and an air filteringdevice 38. Air is drawn inwardly and forced upwardly over the vessel andthe hot water coils and outwardly through the several outlets 15.

Any vapor which is produced in the system will be extended up into thewater supply tank 23 and be condensed and used over again.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

I claim:

A heating apparatus comprising a base, a casing resting upon the base,air outlets on the upper end of the casing, an air inlet at the lowerpart of the casing, a water vessel mounted within the casing andcentrally thereof, heatin coils connected to the water vessel, a waterpump for circulating water through the vessel and heating coils andautomatic water supply means extending to the pump, and electric heatermeans connected to the vessel to heat the water therewithin and saidheating coils being in two sections, one section located above thevessel and the other section surrounding the exterior of the vessel andmeans for causing air to be forced into the apparatus through the inletand over the vessel and the coils thereof, and thermostat means disposedwithin the vessel to control the temperature of the water therewithin.
